Letter from the PresidentIt’s with great pleasure that we present you the 2012 AES Dominicana Statistical Report, highlighting its main assets, operational performance, other lines of business and the electricity market overall. At the end of 2012, AES Dominicana contributed an average of 37.8% of all the energy that was demanded by the National Electric Interconnected System (SENI) with a total of 5,045 GWh injected, surpassing 2011’s energy generation and demonstrating to be the leader in the national electricity market.

78% of this energy was traded in the Contract Market to Distribution Companies, creating significant savings for the Dominican government by providing the cheapest energy in the National System. Our units reached operational milestones, among those were AES Andres and ITABO S.A.’s units, which generated 2,089 GWh and 1,613.6 GWh with natural gas and coal respectively, exceeding both their annual record highs. AES Andres and DPP’s units achieved a high rate equivalent availability factor.

During 2012, the natural gas market achieved sales records, showing growth of 149.55% over the previous year, increasing the sales directed to the electricity sector, which caused AES Dominicana to conduct spot purchases of LNG in the international market to meet rising demand.

AES Dominicana shows its commitment to the country by strengthening its position using natural gas and efficiently restoring the use of coal. Proof of this is the “Máximo Galardón” Silver Medal award we received, in the Major Industry category of the National Quality Awards. Our culture of operational excellence and asset management allows us to contribute to the country’s sustainable development, the environment and the communities we serve.

At the end of this year 2012, AES Dominicana contributed an average of 37.8% of all the energy we sued the National Interconnected Electric System.

AES DOMINICANA BACKGROUND The first investment of AES in the Dominican Republic was the purchase of DPP in 1997 from NGC, an asset that was in their power as a result of their merger with Destec companies. DPP is the owner of Los Mina V and Los Mina VI, two 118 MW open cycle gas turbines.

From May of 1996 until August of 2001, DPP operated under the Independent Private Producer scheme, selling all of its production to La Corporación Dominicana de Electricidad (CDE). Then, after an agreement between DPP and CDE, the contract between both parties was cancelled and a new electricity sale arrangement was established between DPP and EDEESTE, which included a backup contract with the CDE.

In 2000, AES confirmed its commitment to the long-term development of the Dominican Republic by constructing AES ANDRES. The project included a combined cycle of 319 MW, a liquefied natural gas terminal and a gas pipeline connecting to the DPP power station.

In December of 2000, AES took another important step when it acquired the assets of GENER, obtaining a partici-pation of 25% in the ITABO S.A. power plant.

Since May 1st, 2003, Dominican Power Partners operates to supply its electricity sales contract with EDEESTE, selling its excess generation and buying what it needs in the spot market.

Also in 2003, AES ANDRES began its operations and became the most efficient power station of Latin America, representing a jump towards sustainable development for the country using clean energy. This new investment improved the strategic position of the country that formerly depended 90% on petroleum derivatives to supply its electricity needs.

In 2006, AES Dominicana acquired another 25% of the ITABO S.A. equity, formerly owned by El Paso. AES, now with 50% of ITABO’s equity, took control of the operative and administrative areas.

ITABO S.A. INTERNATIONAL PIER

The International Pier of ITABO is located in the coastal area of the ITABO power plant in the municipality of Bajos de Haina in the province of San Cristobal. The pier is located next to the western port of Haina, approximately 8 kilom-eters southwest of Santo Domingo’s western quadrant.

Since 2006, ITABO International Pier has been operating as a reception point for mineral coal, which is utilized in its vapor units, adding a greater degree of autonomy to the process and reducing the overall cost of coal.

The pier extends 535 meters into the sea. It has a system to transport solids with the capacity to load and unload bulk products. In addition, it has a mooring system with six (6) tugboats, four of which serve for the ship’s arrival and two for the ship’s engagement to the pier. It also has a signal system for approaching vessels, located in two towers with adjacent lamps, as well as water lighting tracks and a lighting system in one of the tugboats.

CRyOGENIC DISTRIBUTION TERMINAL

In 2009, AES Dominicana decided to invest in the first LNG tank loading terminal in Latin America, for the distribution of liquefied natural gas

directly to other customers besides AES. The advantage of using liquefied natural gas is the ability to carry higher energy content to distant

locations without incurring losses during transportation.

The LNG tank loading terminal has two loading bays (with the possibility of doubling the capacity) and a loading rate of 68 m3 / h, which means

that the average customer service time (from admission to the complex to the departure) is approximately one hour.

Main Characteristics:

Fourteen (14) meters deep: Enables the docking of vessels like Handymax (45,000 mt) and Panamax (65,000 mt).

Auto-discharging vessels required.Discharge Capacity of 1,200 metric tons per hour.

In 2011, Estrella del Mar II, a Bi-Fuel power plant that runs with natural gas and Fuel Oil #2 that belongs to the Transcontinental Capital Corpo-

ration group, began its operations. This generation plant gets natural gas through a pipeline connected to gas station # 4 of DPP in Los Mina.


28 29

Since 2007, two years after AES Andres signed its first natural gas supply agreement with a local distribution company, AES Dominicana has been

at the forefront of the business in selling natural gas, opening the door to nationwide distribution into new markets that previously could not enjoy

the advantages of this fuel.

Today, AES Andres is the only distribution ter-minal of liquefied natural gas in the Dominican Republic, as well as the first to be installed in

Latin America. This adds value by contributing to the evolution and diversification of the national

energy matrix.

The following chart shows the percentage of natural gas that AES Andres sold in the Domini-

can market in 2012 separated into three eco-nomic sectors: Industrial, Electricity Generation

and Transportation (Natural Gas Vehicles).

WHOLESALE ELECTRICITy MARKET

BRIEF HISTORy OF THE DOMINICAN ELECTRICITy SECTORIn 1997 the capitalization process began. It was instituted due to serious problems in the electricity market caused by a deficit in energy generation, poor quality service and a lack of capital investment for the development of the electricity sector.

The capitalization process was formalized in June 24, 1997, with the pub-lication of the State Companies Reform Law. Before this process, genera-tion, transmission and distribution assets in the Dominican Republic were owned by CDE, who by law, was the only entity authorized to operate in the electricity sector.

In the mid 90s, CDE signed several power purchase agreements with inde-pendent power producers; increasing the system’s installed capacity with private capital. During this period, the sector was regulated by a series of administrative resolutions issued by the Industry and Commerce Ministry.

Through the different stages of the capitalization process, the assets held by CDE were divided into eight state-owned companies: CDEEE, a parent holding company; three distribution companies: EDENORTE, EDESUR and EDEESTE; three generation companies: HAINA, ITABO, HIDRO; and the power transmission company ETED.

In 1999, the three distribution companies and the two thermal genera-tion companies were capitalized through the sale of 50% of the stocks to private investors. The Dominican Government remained with 49% of the stocks and the last 1% was sold to the employees of these companies.

In July 2001, the Electricity General Law was issued, establishing the institutions of the sector and the rules under which it will operate. In July 2002, the Electricity Gen-eral Law Rulebook was issued, completing the electrical sector’s new legislation.

In 2007, law number 186-07 modified the Electricity General Law and its Rulebook. The new law’s goal was to penalize electrical fraud and establish other measures to obtain the electrical sector’s financial viability.

The table below allows us to view the installed capacity of the system

by Generation Company and by technology.

TRANSMISSION

The Electrical Transmission Company of the Dominican Republic (ETED) is a state-owned company with the primary objective of building, oper-ating and sustainably managing the grids and substations of the electric interconnected system of the Dominican Republic, in order to provide quality service at reasonable prices.

The electrical infrastructure consists of a total length of 4723.95 km of lines at 345, 138 and 69 KV, where the 345 KV network, which links the North Zone with the area of Santo Domingo, is the most economically important and functional one. It has a length of 129.9 km at a maximum transmission power of 1200 MVA per circuit.

In addition, the National Transmission System consists of approximately 2660.93 km of transmission lines at 138 kV and can be referred to as the Sub-backbone network; also 1933.13 km of 69 kV lines. It operates and maintains approximately 85 substations, owned and shared.

Because of its radial configuration, the National Electric Interconnected System is divided into four zones: Santo Domingo Zone, South Zone, North Zone and East Zone. The most important substations of these zones are: Palamara and Hainamosa in the Santo Domingo Zone, Pizarrete in the Southern Zone, Bonao II and Canabacoa in the Northern Zone and San Pedro II in the Eastern Zone.

ELECTRICITy DISTRIBUTIONThree distribution companies manage the electricity distribution of the national interconnected grid:

EDESUR Dominicana, S. A.EDENORTE Dominicana, S. A.Empresa Distribuidora de Electricidad del Este, S. A.

These companies obtain their energy from the electric system through high voltage bus bars, which are later transformed to minor tensions and then conducted through each company’s grids within their zones of concession until these reach their final users.

The distribution company lines within the national grid contain a mechanism of automatic load shedding, implemented in various distribution company substations through low frequency and low voltage relays, which serve to disconnect the electrical load automatically through different phases. This mechanism is reviewed and updated periodically by the Organismo Coordinador, the independent market operator.

ENERGy BALANCE

In the following table we can observe the monthly energy balance during 2012. This includes the net injections of the generation companies as well as the distribution companies and non-regulated users’ withdrawals; the last two have been grouped independently from the generation companies with which they have a power supply contractual arrangement.

In 2012, the total injection of electrical energy in the system was 13,329 GWh. The companies who supplied the most were AES Andres with 15.7%, HIDRO with 13.3%, ITABO S.A. with 12.1%, DPP with 10.1%, HAINA with 9.7% and SEABOARD with 9.0%. AES Dominicana contributed 37.8% of the energy in the Electricity Wholesale Market, reaching the highest market share in the generation sector.

MAxIMUM DEMAND

The system’s maximum demand is the highest power consumed by distribution companies. Generally, this happens during system peak hours. Maximum demand is data used in capacity recalculation since a preliminary estimated maximum demand is used prior to computing these figures. The system re-munerates only the maximum capacity effectively recorded as demanded during the year. The following table shows 2012’s monthly power production and power consumptions during system peak hours.

CAPACITy SPOT PRICE AND CONNECTION RIGHT

Capacity’s marginal cost is the price for which the transactions of Firm Capacity are valued, and is determined by what is established in Article 278 of the Regulation of the General Law of Electricity. This also corresponds to the monthly calculations for the Connection Right Unit Price, which is established in Article 364. At the end of 2005 the Superintendence of Electricity emitted Resolution No. 108 in which they ordered to recalculate the Connection Right Unit Price using the definitive capacity transactions.

FIRM POWER: The power that can be supplied by each generating unit during peak hours, with a high level of security/safety.

FREQUENCY REGULATION: Actions necessary to maintain frequency within the permissible tolerances defined for the system. The OC establishes the regulation parameters, and the generator companies are responsible for providing service through their control centers.

FUEL OIL: A petroleum derivative obtained as a residue after the distilling process. Being a fuel, which is heavier than those that can be distilled at atmospheric pressure, Fuel Oil is used as a fuel for electrical energy plants, boilers, and ovens.

GAS TURBINE: A machine composed of an air compressor, a turbine especially designed for this purpose, and an electrical generator. The turbine converts thermal energy from fuel, which is produced as a result of the expansion of hot gases from the explosion of the mixture of compressed air, fuel, and flame, into mechanical energy that is used by the electrical generator to produce electricity.

HyDRAULIC TURBINE: A machine that uses kinetic energy and power from water to produce a rotation movement which, transferred through an axis, directly moves a machine or generator that transforms mechanical energy into electrical energy.

LIQUID NATURAL GAS (LNG): Natural Gas processed to be transported in liquid form. It is the best alternative for transporting and storage because when transformed into liquid as atmospheric pressure and –163º C , the liquefaction process reduces the volume of gas by 600 times.

MARGINAL CENTRAL UNIT: This refers to the generating unit or units, which at optimum load dispatch increase their generation when the demand is marginally increased.

MARGINAL SHORT-TERM COST: The variable costs necessary to produce one additional unit of energy, considering the demand and the genera-tion infrastructure available.

MAxIMUM ANNUAL DEMAND: The maximum gross half our demand, during a calendar year, of the total of the generator units of the system, oc-curring within the system´s peak hours.

NATURAL GAS (NG): A mixture of gases that is frequently found in fossil beds, alone or accompanied by oil. It is composed mainly of methane in quantities greater than 90 to 95%, and in addition, usually contains other gases such as nitrogen, ethane, CO2, and traces of butane or propane, as well as small proportions of inert gases such as carbon dioxide and nitrogen.

NON REGULATED USER (UNR): A user of the electrical service whose monthly demand exceeds the limits established by the Superintendency in order to be classified as a publicuser, and who fulfills the requirements established in the Regulation of the General ElectricityLaw.

OWN CONSUMPTION: The energy consumed by the auxiliary systems of a central unit orSubstation.

PEAK POWER: Maximum power on the annual load curve.

PRIMARy FREQUENCy REGULATION (PFR): Power that a generator unit can vary by automatic action of its system in the face of changes in the system’s frequency.

RIGHT OF CONNECTION: The difference between the total annual cost of the transmissionsystem and the right of use estimated for the year. The procedure to determine the right ofuse is established in the Regulation of the General Electricity Law.

SECONDARy FREQUENCy REGULATION (SFR): Power which a generator unit can vary, or modify, by automatic or manual action of its system of regulation in a sustained manner.

SPOT MARKET: The market for transactions of short-term sale and purchase of electricitynot based on term contracts where economic transactions are performed at Marginal ShortTerm Energy Cost and at Marginal Power Cost.

STEAM TURBINE: A machine that transforms thermal energy from fuel into mechanicalenergy. Through a process of generation of steam produced in a boiler, which createsconditions of high temperature and pressure. The kinetic energy of the steam is used by theturbine to mechanically generate electricity.

VARIABLE PRODUCTION COST OF A THERMAL ELECTRICAL MACHINE: This corresponds to the cost of fuel placed in the plants, and used in the production of electrical energy, multipliedby the average specific consumption of the machine plus the variable non-fuel cost.
